MARKING BUTTON.-

Specification of Letters Ifatent PavtqvgM-,ed Febyzl.

' Application filed April 26, 1918. Serial No. 230,945.

Beit known that I, HENRY V. BAU, a citizen of the VUnited States, residing at Brook-- lyn, in the county of Kings and State of New York, have invented certain new andv useful Improvements in Marking Buttons,

`of which the following is a specification.

My invention relates generally to buttons and particularly to buttons of a ,type that is intended to bear indicating characters to be Vused in marking various materials.

Devices of this general nature are well known in the art and they have usually consisted of a tubular rivet formation, the stem of which was adapted to be fastened in the material to be marked and the flattened head of which had a sheet metal disc bearing the -marking indicia applied thereto with the edge of they disc clinched over 'the edge 'of the lflattened vrivet head. yThis construction presented a number of serious disadvantages. One of these disadvantages consisted inthe necessary use of metal for the facet member bearing the indicating character in order to provide a sufficiently substantial construction to withstand the clinch- VVvantage of the construction described resided in the vrtendency which the unsupported icenc tral portion ofy the face member had to collapse into the underlying open endV of the g n in section a View ofa preferred form of the tubular stem to such an extent as to affect the legibility of the indicating character and render it difficult vto read. On the other hand, when the face member has retained its position and has not been bent into the underlying opening, the exposed position of the face member has rendered the indicia carried by it peculiarly susceptible to damage by abrasion or other injury occasioned by mechanical contact with surrounding objects.

The principal object of the present invention is to provide a marking button of the general type indicated in which the disadvantages referred to as existing in prior devices are overcome. v

With this and other objects in view, one feature of the invention consists in the provision of a button in which the upstanding flange of the cup-shaped body member is Vhereinafterdescribed.

Stilll another feature' of the invention resides'inthe interposing of a rigid supporting member between the'indicia carrying:

face member'and the end of the "tubular stem to prevent the collapse of the face member into the adjacent underlying coreof the stem. Y. f

Other features of the invention will be In the drawings,A l ll1`igure 1 is a plan view'of a button' embodying a preferred form of: the invention.

IIn Figure Qofthedrawing there :isshown invention in which a main body member is indicated at 1 with the upper part of the rim of its cup-shaped top upset onto the edge of the yface member 2 bearingv the` char-vl acter 3. The body member lis preferably formed of sheet metal and has for a stem a tubular rivet formation as indicatedat 5j, the tubular stem 5 being adapted to be j passed through any desired sheet material 6 to which it is `desired to apply the marking button and to have its end clinched or upset to hold the stem and the 'button in place', in an Obvious manner. 1

It is the practise to make marking buttons of this general nature in comparatively small sizes so that the area of the central portion of the face member overlying the adjacent open end of the tubular stem may comprise a relatively large proportion of the total area of the face member and for that reason renders the indicating character on` the face member very dificult to read when, for any reason, the central portion of the face member has collapsed into the underlying open end of the tubular stem. With a view to correcting this defect, l have adopted the expedient of interposing the bridging member shown in plan view in Figure l of the drawing betweenthe face member 2 and the bottom of the cup-shaped head ot the body member 1 and have thus eifectually prevented any possibility of a collapse of the face member into the core in the stem. The core bridging member 4 may be made of any suitable sheet material having a sufficient degree of thinness with the necessary rigidity to reinforce the face member and prevent its collapse into the hollow stem.

lt Will be seen that the raised portion of vthe iiange 8 which is formed not only obviates the necessity of using a metallic material for the face member 2 and thus pro- -Vides for the use of inexpensive material such as paper, but that the raised formation presented by the flange serves to protect the surface of the face member 2 and theV character 3 inscribedrthereon from defacement of" any sort. rlhe effectiveness of this protection is enhanced by the relatively small `diameter of the buttons as Ythey are Vused in actual practise.

las a further means of protection against injury of the face member e, a special cover member 7 made of thin and transparent material such as sheet Celluloid, may be addedV ent in prior devices, and that is inexpensive toV manufacture and substantial and durable in character. The button as thus produced is easily vattached to the desired material by Ysimply pressing the tubular rivet forming 1 ,lioness the stem 5 through the material, or through a hole previously formed therein, and clinching the end ofthe stemon the vunderside of the material.

Having thus described my invention, what l claim and desire to secure by Letters Pat ent of the United States is:

1. iV button comprising: a disc-shaped face member, a body member having an edge thereof upset over the edge of said face member toform a raised flange around said edge, a. tubular stem on said body member having an open end of the core therein in contiguous relation to the underside of the central portion of the face member, and a bridging member formed of sheet material interposed between said face member and the'core in said tubular stem.

2. A marking button comprising: an indicia bearing face member, a cup-shaped body member serving as a seat for said face member and having the rim thereof clinched over the edge of said face member to form a raised protecting flange thereon, a Ytubular stem on said body member, and a sheet metal .Y

bridging member for preventing the col lapse of said face member into the core of said stem, said bridging member Vhaving supporting engagement with said f'ace member along two diameters of said face .member substantially at right angles Yto each other. y A

3. A marking button comprising: an indicia bearing face member, a cup-shaped body member serving as a seat for said face member and having the rim thereof clinched over the edge of said face member, a tubular stem on said body member, and a bridging member formed of rigidsheet material interposed between vsaid face rmember and the core of said tubular stem and extending across the seat formed by saidA cupi-shaped member.
